I seem to be having a problem with my center channel i currently have a Definitive Technology CS-8060HD center channel with a built in woofer. when i place this woofer on my television stand it seems to have a very faint popping noise that comes out of the woofer. when i move the speaker to the other room to no feedback from the woofer. even on the floor next to the stand not feedback but as soon at is touches the stand i get feedback from the woofer.
Thanks for all the help in advance.
